Objectives:
To investigate if sleep stability decreased in medical interns during on-call duty.

Conclusions:
The medical interns had significantly reduced stable sleep, and displayed increased latency to the first epoch of stable sleep during the on-call night shift, compared to the pre-call and on-call duty-free nights. 

Practical Significance:
This reliable ECG-based method provides a simple and objective means to evaluate sleep quality in medical staff performing shift work under stressful conditions.
